Did you know you could use:
White Bread and Ketchup
Use white bread to: Dust an oil painting. Gently dab a slice of white bread over the surface to pick up dirt and grime.
Use ketchup to: Remove tarnish from copper and brass cookware. Squeeze ketchup onto a cloth and rub it on pots and pans. They should go back to their coppery color in minutes. Rinse with warm water and dry with a towel.
I did not know these two things could be used for anything other than PB&J and Hot Dogs!
